So my wife approved an iPad 4 purchase because she's sick of hearing me talk about it (heh heh). I'm looking at either a 32 or 64 gig wifi, and had a couple questions that might help in the decision of which would be best for me. 1) I've got about 15 gigs of music. I don't know if I would really listen to music on the iPad, but it would certainly be nice to have it all on there if this is my multimedia/entertainment device. How often do you find that you use iTunes on your iPad? 2) What is the average app size? I'm assuming they are larger than the iPhone apps? 3) I know they have iPad apps and iPhone apps; if I've already bought the iPhone app, do I get a free download for the iPad version, or do I have to pay again? Also, if I buy an iPad app, can I use it on my phone as well? 4) Around how many apps do you have and about how much space do they take up total? I know this depends on the apps, but maybe I can get a ballpark idea. I just don't want to get a 32 gig and then have to be removing stuff all the time. I would also like to be able to load a couple movies on it for flights without having to remove anything. My heart says 64 gig, but my wallet says 32 gig. Thanks. EDIT: Also how is in store stock at this point? Good chance of black 32 or 64 gig wifis?
